Can clothing systems and human activities in operating rooms with mixing ventilation systems help achieve 10 CFU/m3 level during orthopaedic surgeries?
Cao, Guangyu; Pedersen, Christoffer; Zhang, Yixian; Drangsholt, Finn; Radtke, Andreas; Langvatn, Håkon; Stenstad, Liv-Inger; Mathisen, Hans Martin; Skogås, Jan Gunnar (Journal article, 2021)The level of airborne microbial contamination in operating rooms (ORs) is an important indicator of indoor air quality and ensures a clean surgical environment. It is necessary to research how different factors affect the ... -
Distribution of droplet aerosols generated by mouth coughing and nosebreathing in an air-conditioned room
Zhang, Yixian; Feng, Guohui; Bi, Yang; Cai, Yilin; Zhang, Zheng; Cao, Guangyu (Peer reviewed; Journal article, 2019)The objective of this study is to understand the distribution of droplet aerosols in an air-conditioned room, which is very important to comprehend how infectious bacteria and viruses transmit from person to person through ... -
Experimental measurements of surgical microenvironments in two operating rooms with laminar airflow and mixing ventilation systems
Cao, Guangyu; Kvammen, Ingeborg; Hatten, Thea Amalie Solberg; Zhang, Yixian; Stenstad, Liv-Inger; Kiss, Gabriel; Skogås, Jan Gunnar (Peer reviewed; Journal article, 2020)At present, laminar airflow (LAF) systems and mixing ventilation (MV) systems are two commonly used ventilation solutions for operating rooms (ORs) to ensure the required indoor air quality. However, recent studies have ... -
Experimental study on the effect of exhaust airflows on the surgical environment in an operating room with mixing ventilation
Xue, Kai; Cao, Guangyu; Liu, Meng; Zhang, Yixian; Pedersen, Christoffer; Mathisen, Hans Martin; Stenstad, Liv Inger; Skogås, Jan Gunnar (Peer reviewed; Journal article, 2020)Due to the requirements of indoor environment parameters, including temperature, humidity, air speed and indoor quality, the design of the surgical environment is a very complex task. However, with limited studies on the ... -
The impact of air change rate on the air quality of surgical microenvironment in an operating room with mixing ventilation
Zhang, Yixian; Cao, Guangyu; Feng, Guohui; Xue, Kai; Pedersen, Christoffer; Mathisen, Hans Martin; Stenstad, Liv-Inger; Skogås, Jan Gunnar (Peer reviewed; Journal article, 2020)Transmission of airborne microbe-carrying particles (MCPs) is one of the key factors causing surgical site infection during surgical procedures. In operating rooms (ORs) with mixing ventilation, air change rate may determine ... -
